Japanese sake is very sensitive to temperature so it should be kept in the refrigerator. Once it is opened, we have to drink it as soon as possible because the taste will change. Therefore, 720ml is too big for those who want to drink it occasionally and drink a little bit. It may be unsatisfactory for those who drink a lot at once.
However, for those who have hesitated or shy away from sake until now, this miniature sake will help you feel closer to the history of sake.
Extremely cold unrefined sake was filtered by rough colander. This is good for those who like dry sake.
